Spine SBRT using VMAT [PDF]

Journal of Physics: Conference Series, 2017
Metastases of the spinal column are common amongst cancer patients with approximately 18,000 new cases in North America each year that require urgent treatment. Historically radiation therapy doses have been limited due to the proximity of the spinal cord.

4DCT and VMAT for lung patients with irregular breathing [PDF]

Journal of Applied Clinical Medical Physics, 2021
AbstractPurposeIrregular breathing in lung cancer patients is a common contra‐indication to 4D computerized tomography (4DCT), which may then limit radiotherapy treatment options. For irregular breathers, we investigated whether 3DCT or 4DCT (1) better represents tumor motion, (2) better represents average tumor densities, and (3) better allows for ...
